You've come to the right place for info, questions answered and heartfelt support and at times a good laugh. So welcome Billy and Trish!
There's good reason to be scared but knowing what's happening to you both will help you a great deal with that. Also you'll get solid advise from so many different people here. Some annoying little problems really can be solved in a minute. So please ask questions whenever you feel like it, no matter how big or small the trouble you're having.
The fact that you're sitting together, introducing yourself to one of the best places on the internet, looking for support tells me that you're tackling this monster already.
Billy, there is very fine technology to use a computer with even though your hands might fail you. Many users here write with eye gaze and other gadgets. My PALS (my boyfriend with ALS) is right now trying to get a headmouse approved. If speaking is no problem voice-to-text is great. I use it myself on my smartphone with the Google keyboard (gboard?) all the time.
Trish, if you like you can also create an account of your own. Caring for someone with ALS it can be hard sometimes to relate to even close friend and family how you feel. Try to take them with you by telling them how you feel and why. But sometimes that too is work and you can just drop in the CALS subforum, where caregivers give support to each other, for a rant or a cry. We get you immediately.
Sending you strength to get through the initial shock!
